OAuth Authorization Code flow, with tokens kept server-side: refreshing needs
the client secret, so the browser never holds a Spotify token — it asks this
instance what is playing and this instance calls Spotify.
The callback arrives as a plain browser redirect with no Authorization header,
so the OAuth state carries the user id signed with the instance secret and is
compared in constant time; without that, anyone could bind their Spotify
account to another user.
Activities are now tracked per producer. pushActivities replaced the whole
list, so the desktop game detector and Spotify would erase each other — losing
exactly the case this is for, a game and Spotify at once.
Polling backs off when the tab is hidden and keeps the last known track on a
network error rather than reporting 'stopped listening'. A rejected refresh
token (access revoked on Spotify's side) drops the row so the UI stops
claiming a live connection.
Scope is read-only: user-read-currently-playing and user-read-playback-state.
Per the fork's language rule, the new UI ships in en and pt-BR, and this
round also translates the privacy panel.
Adds an explicit override for the federation transport URL returned by
getOurOrigin(). When unset, behaviour is unchanged (https://${DOMAIN} ->
http://localhost:${PORT} dev fallback). Intended for reverse-proxy /
dev-without-TLS deployments where the public origin must be advertised
explicitly (typically http://...) and differs from the bare DOMAIN
value used for federated identity.
Wired via config.publicOrigin (envOptional('PUBLIC_ORIGIN')) so the
override flows through the existing config layer rather than scattering
process.env reads. Trailing slash is stripped for symmetry with
peer.origin storage.
docs/systems/federation.md gets a "Public Origin Override" subsection
under §14 Background Workers documenting the resolution order.
- SSRF protection: DNS resolution + private IP blocking on metadata fetcher
- Upload security: CSP/X-Frame-Options headers, SVG forced download, nosniff
- Auth hardening: JWT secret min length, password min 8 chars, token revocation via password_changed_at
- Attachment ownership verification before linking to messages
- Message length limit (4000 chars) enforced on client and server
- Asset URL validation on avatar/banner updates
- Federation instance validation (domain regex, origin scheme, length limits)
- DB indexes on all FK columns for query performance
- Migrations: nullable moderator columns, dm_messages reply_to FK constraint
- File cleanup on avatar/banner replacement and space deletion
- Fastify trustProxy, AbortController on fetches, typing map size cap
- Add Backspace-design-prototype.html: finalized "Aether Drift" design
language with warm matte surfaces and subtle frosted glass accents
- Update CLAUDE.md with DESIGN SYSTEM section and remove Discord clone references
- Rename all Opencord references to Backspace across the full codebase
- Archive outdated design experiments and Discord-specific assets
- Add science-backed accessibility fallback (prefers-reduced-transparency)
